I have 2007 250 and every time I start, as is normal, the oil pressure light would come on for a second or two and then shut off. The other day it stayed on so I shut the bike off and didn't ride that day I started it again when I got home from work and the oil light stayed on for about 10 seconds and then went off. Oil levels were fine and the engine sounded healthy. But now I've noticed that the light doesn't come on at all. Not when the key is in the 'on' position and not for a second or two when I start it. Any ideas? Bad bulb? Bad sender unit? Thanks!
